REGISTER OR VENTILATOR.

Specification of Letters Patent.

Patented Dec. 13, 1910.

Application filed September 14, 1908. Serial No. 452,840.

To all whom it may concern.

Be it known that 1, JAMES H. BAILEY, a citizen of the United States, residing in the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Registers or Ventilators, of which the following is a specification.

My invention relates to registers or ventilators of that class which usually have a frame or body portion rectangular in shape adapted to be placed in the end of an air flue on the walls or floor of a room, and consists of details of construction hereinafter pointed out.

In the accompanying drawings I have shown one form which my invention may take.

' Figure 1 is a front perspective view of a portion of the register or ventilator with the usual face-plate removed. Fig. 2 is a rear perspective view of the same. Figs. 3 and t are perspective views of portions of my register or ventilator showing details of construction. Fig. 5 is a plan view of the blank from which one of the end plates of the frame is made.

The frame or body portion of the register consists of end pieces 1 and 2 and side-pieces 3 which cooperate with the end-pieces to form a rectangular frame tapering slightly from that side on which the face-plate usually rests. The end-piece 1 is formed from a blank shown in Fig. 5, and as shown in Fig. 1, comprises a main body portion hearing seats 6 for pivots on the valves and ex tensions 7, 8 and 9 engaging apertures in the side-pieces in which they are upset, thereby rigidly connecting the four portions of the register frame together. It will be noted that the rivet projection 7 is formed on an extension of the end-piece 1 which is turned in at right angles so as to engage the side-piece of the frame a short distance in from its end. For a similar reason the por tion adjacent to the projection 8 is indented and the lower portion of the end-piece 1 is depressed, so as to allow the projections 9 to engage the side pieces inward from their ends, and also to allow the pivots on the valve to extend through the end-piece without extending beyond the side-pieces by which they are, in a measure, protected when set in position. The side-pieces are turned in at their tops 10 and overlap the extension on the end pieces carrying the rivet 7, thus valves and also holds the said connecting rod in the frame whether the face-plate is attached to the register or not. In addition to the guide 12 there may be 011 the inturned portion of the end-plate two or more pro jections 18 for receiving the screws which hold the face-plate in position on the register.

The end-plate 2 is similar in all respects to the end-plate 1, excepting that the guide 12 may be omitted, inasmuch, as there need be a connecting-rod for the valves at only one end; and also the apertures 6 for receiving the pivots on the valves may be replaced by screw threaded apertures, so that the other end of the valves may be carried on removable pivots.

When the register is to be used in the floor, it is usually desirable or necessary to provide reinforcing bars 1 1 in the frame against which the face-plate may rest. WVhen these are used it is desirable to provide in the end pieces of the frame apertures 15 forming seats for the reinforcing bars which may be recessed at one end 16 to receive the inturned portion carrying the guide 12, so that they may, throughout the rest of their length, be in direct contact with the under side of the face-plate.

The valves 17 may be provided with longitudinal strengthening ribs in the usual manner and have in an upturned portion at one end holes to engage the removable pivots in the end-piece 2 while at the other end they have upturned portions carrying pivots which engage the apertures 6 in the end-piece 1. The latter upturned portions are also provided with slots which engage projections on the connecting-rod 18 whereby the valves may be opened and closed in the usual manner. The connecting-rod 18 rests at its lower edge upon the revolving pivots of the valves which act as roller bearings for the connecting-rod, and there is projecting upward from the connecting-rod a thumb-piece 19 for actuating it. The thumb-piece 19 extends through, and is guided in its movement by, the guide 12 on ing-rod pressed down onto the valve pivots I which act as roller bearings therefor.

The whole device as described may be made of a small number of pieces of pressed sheet steel which, by my construction, readily lends itself to produce a light but strong register which is cheap to manufacture, inasmuch, as the assembling of the parts is very simple and readily performed. After the sides and ends of the frame have been put together, the connecting-rod is placed in position and the end of the valves adjacent thereto are inserted and by means of the guide 12 the portions already assembled are held in place while the removable pivots at the opposite ends of the valves are inserted when the assembling is completed.

It is obvious that changes might be made in details of construction without departing from my invention.

I claim as my invention 1. In a register or ventilator, a face-plate, a frame comprising two side-pieces and two end-pieces tapering from front to rear the sidepieces being turned over at their top edges onto inturned portions of the endpieces, projections on said end-pieces adapted to engage and be upset in apertures in said side-pieces certain of the projections being on depressed portions of the end pieces and certain of the projections being on inturned portions of the end pieces, inturned portions of said end-pieces forming lugs to which the face-plate may be fastened, an inturned portion on one of said end-pieces containing seats for the revolving pivots of valves, an inturned guide for the thumb-piece of a connecting-rod on said end-piece and integral therewith, an inturned portion on the other end-piece carrying removable pivots on which the valves swing, a connecting-rod riding between the valve bearings on the revolving pivots, a thumb-piece on the connecting-rod, a leaf spring between the connecting-rod and the guide for the thumb-piece, pins carried by said connecting-rod engaging slots in upturned portions of the valves by which the valves are actuated, a plurality of valves, bearings at one end of the valves, removable valve pivots on one end-piece engaging the bearings, revolving pivots at the other end of the valves engaging the hearings in the other end-piece, upturned portions on the valves, slot-bearings for the pins on the connecting-rod in the upturned portions of the valves, rods engaging and extending be tween the end-pieces and bearing against the face-plate to reinforce the face-plate and recesses in the rods to receive the inturned guide for the thumb-piece of the connecting rod.
